I have 2 EP600'S, 5 channels of krell class A power that doubles down to 4ohm @500w, and 2 channels that double down to 2ohm @1200w.
All of this is on a single 15A breaker.. The HT has never tripper the breaker. The real world power draw is much less than people assume..
It is so much less than people think, I think. The power requirements are transient in nature and not all speakers at once as you well know. I too am way over powered and could not possibly drive the amps to a point they would deliver full power ,especially with efficient speakers like axioms.
Currently on one breaker . 60in Plasma TV (350w) , bdplayer ,dvr, 2 emo amps 8 channels @300w , air cleaner, lamp , xbox one, xbox 360, AVR, backlight for tv, 16 port switch, 2 subs and a bunch of wall warts.
DOG is GOD spelled backwards.
I blame my terseness on my keyboard.
